claims. (c1. 311-1) This invention relates to a portable table to beused by chiropractors in making spinal adjustments. i

`may be easily moved onto the table.

It is accordingly an object of the invention to provide a chiropractictable which will be portable and be readily carried by one person.

A further object of the invention is to provide a chiropractic tablewhich will enable the cushions thereof to fold and thereby permitlongitudinal collapsing of the table.

A stillfurther object of the invention is to provide a portablechiropractic table which will be light in weight and whichwill retainthe basic pad adjustments found ou larger tables.

l A still `further object of the invention is to provide a simple meansfor adjusting the cushions to accommodate various patient weights.

With these and other objects in view, the invention consists of certainnovel features of construction as will be more fully described and moreparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view of a portable chiropractic operatingtable in the folded position ready for carrying, a carrying strap beingattached thereto;

Figure 3 is a top view of the table in the same position asin Fig. 2;

Figure 4 is an end v iew of the table in operating position taken fromthe lefthand end of Figure 2 with certain parts omitted for clarity anddrawn to an enlarged scale; FigureS is a sectional view taken on lines5-5 of Figure Figure 6 is a sectional view taken on lines 6--6 of Figure5; and

j. @Figure 7 is a sectional view taken on lines 7-7 of Figure 5.

"` Referring now to the accompanying drawings, there is shown` aportablechiropractic table having two leg members.10 and 11 which are joinedtogether by extendable ,frames or pivoting X frames 12, there being twosuch 2,965,425 Patented nee, zo, 1960 FCC lThe scissor or X frame l2 ismade up by a plurality of generally flat bars which are pivoted to eachother at the ends thereof and also at the central portion. Each framehas one free end thereof pivotally attached to the yvertical leg pieces10' and` 11 as at 13 and 14, the other free ends of the frame beingattached to the upright members 10 and 11' by a bolt and thumb screwarrangement 15, the bolt being adapted to slide in slots 16, 17 in theleg members 10 and 11 respectively. Accordingly, when the leg members 10and 11 are moved close together,

the slots 16 and 17, while in the extended position as .shown in Figure2, they will lie at or near the bottom thereof. Accordingly, it will beseen that with this arrangement the two leg frame sections 10 and 11 maybe brought together or separated and at all times will remain inparallelism to each other.

On to the frame structure just described, there is mounted a pair ofhead cushions 1S, a chest cushion 19, an abdominal cushion 20, and a legor lower body cushion 21. The head cushion 18 is made of two generallyrectangular padded sections 18A and 18B which are joined together ateach end by transverse support members 22, 22 and are hingedly relatedto the horizontal member 10" as by hinges 23, 23. The head cushion issupported in either a horizontal or plurality of adjusted positions `bymeans of a support bracket generally designated 24. This bracketconsists of a rst member 25 (see Figs. 4 and 5) which is pivotallyrelated to the transverse member 10A of the leg frame 10 by au anglebracket 26 and along the longitudinal extent of themember 25 is an`elongated slot 27 provided with a plurality of detents 2S.

The second part of the bracket 24 consists of anoter bar `29 which atone end thereof has a pin 3i) that is adapted to be received in theelongated slot 27 and engaged nin one tially in a straight line, oneedge of the bar 29 is provided with an overhanging lip 31 (see Fig. 6)which engages one edge of the bar 25. The other end of the bar 29 isprovided with a pin 32 which is adapted to be receivediin a slot 33having two detents 34 all of which are formed in an angle bracket 35attached to transverse member 22. It will be apparent from the abovedescribed structure that the head cushion 11S may be placed in a varietyof adjusted positions by changing the point of engagement of the pins 32and 30 with their respective slots having the detents 34 and 38respectively. Further, it will be apparent that this particularstructure will easily jacknife, the part 25 rotating in a generalclockwise direction as viewed in Figure 5 while the part 29 rotatesabout pivot point 30 in a general counterclockwise direction to theposition shown in broken line. This permits complete folding of the headcushion 18 parallel to the leg frame structure 10A, a cutout portion 36being provided in the bar 29 thus permitting saidl bar to liesubstantially parallel to the leg member 10, the cut out 36 embracingthe transverse member 10A.

The chest cushion 19 is hingedly related to the upper horizontal member10" of the leg frame structure 10 by hinges 39, 39'. Similarly theabdominal cushion 20 is hingedly related to the upper horizontal member11" by hinges 40, 40' and since the two cushions are supported inadjusted position in identical manners, only the chest cushion 19 willbe described and similar but prime numerals will be used for like partsthat are associated with the abdominal cushion. Referring now to Figure5, the

.chest cushion 19 may be supported in a general horizontal j planethrough a bracket assembly generally designated 41.

This assembly consists of two bars 42 and 43 which are pivotally relatedto each other as at 44, the other end of the bar 42 being hingedlyrelated to the underside of chest cushion 19 by means of an anglebracket such as 45 and j. .e the other end of the bar 43 being hingedlyrelated to the transverse member 10A of the leg frame 10 by means of anangle bracket 46.

From-the above description, it will be apparent to those skilled in theart that there is described herein a portable chiropractic table with'allbf the necessary cushions for performing.,body adjustments andparticularly one which is extremely portable, which portability maybe,enhanced by constructing the rigid and main frame'rnembe'rs'frr lightand yeptstrong metallic materialssuch as `the various alloys of aluminumand magnesium that are now available. Further the table is cap/ableof"all the necessary adjustments that are used in making the bodyadjustments and is of simple construction requiring no unusual servicingthrough use.
